I check some other similar questions here, but there was always the problem, that they wanted to call the constructor without parameters, while the constructor had parameters. But the constructor is undefined android I don't see this problem in my code. Could you please help me? Thank you! I get the error message: The constructor Node(int) is undefined The class with the main method: package LLP; public class LinkedList2Test { public void main (String args[]){ LinkedList2 test = new LinkedList2(); test.add(13); test.add(10); test.add(21); } } The LinkedList2 class package LLP; public class LinkedList2 { Node head; Node tail; public void add(int data){ **Node node = new Node(data);**// **THE PROBLEM is here** if (tail == null){ tail = node; head = node; } else { tail.nextNode = node; tail=node; } } } The Node class package LLP; public class Node { int data; Node nextNode; public Node (int data){ this.data = data; } } As I see, in the main method I give in an integer, for example '13'. The add method receives this integer and calls it as 'data' And I would like to create the node with that 'data' Node's constructor needs just one integer, which would be 'data' so now 13 for example Why does it not

The error was "The constructor 'TitleBar' is undefined" I reviewed my code with the Objects tutorial in this page and the only differencfe was the class name. Is there a reason for the code not is undefined working with TitleBar as a name?

What do you want to name TitleBar? the class? or the instance?

Any help? arjanforgames, Oct 1, 2013 #1 Offline The_Doctor_123 My BukkitDev ProfileMy Plugins (3) First of all, you cannot cast the world name to a world. You will need to use Bukkit.getWorld(String). You're also casting what it seems to be, integers, to a location.. No. You cannot do that, how would the program even know if you're talking about the x, y, z, yaw, or pitch? Secondly, the Location constructor takes a World, int, int, and int.

Offline Fozie Emm the problem is that you trying to cast integers to Location and Strings to World do instead Code:java GameOneLocation =new Location(Bukkit.getWorld( getConfig().get("Path.world")), getConfig().get("Path.X", getConfig().get("Path.Y", getConfig().get("Path.Z"); Fozie, Oct 1, 2013 #3 Offline arjanforgames Fozie I get: "The method getWorld(String) in the type Bukkit is not applicable for the arguments (Object) " arjanforgames, Oct 1, 2013 #4 Offline The_Doctor_123 My BukkitDev ProfileMy Plugins (3) arjanforgames Do you know any Java? You need to cast the object you're getting to a String. Actually, there's a getString() method in FileConfiguration. The_Doctor_123, Oct 1, 2013 #5 Hutchmaster99 likes this.
